How does computer box leakage of electricity do?
The case study of computer box leakage of electricity:
1, transient cause brings about computer box leakage of electricity:
Leakage of electricity of existence of some moment computer also may not be computer box interior advocate board or power source leakage of electricity brings about, some moment can discover because transient cause is brought about,box leakage of electricity is, what for instance box and other electric equipment place is too close or box lay a finger on is waited a moment to the electrical wiring of broken skin, bring about box leakage of electricity thereby. To the box leakage of electricity that this kind of transient cause brings about, settle way actually very simple, discover when us box is put when leakage of electricity, the examination has what electric equipment to perhaps come up against what electrical wiring to wait near next computer box, the position below shift can be solved.
2, immanent cause brings about computer box leakage of electricity:
Immanent cause brings about computer box leakage of electricity is circumstance of the commonnest computer leakage of electricity, so is computer box in-house what hardware is easy Where is leakage of electricity? This actually very good also know, basically find what hardware and box to have a contact can, for instance power supply causes box leakage of electricity the most easily, another is advocate board if be not installed,reach the designated position or, certain perhaps component brings a foot to touch take box case appear easily also phenomenon of leakage of electricity.
The processing technique of computer box leakage of electricity:
1, discover leakage of electricity, whether does the electric flashboard that we should affirm to we use above all have good ground connection design, if did not change immediately (the electrical outlet of relatively common report of the form that enter a wall in including household) , had good ground contact, even if is generation leakage of electricity, also can reduce harm and loss least.
2, open box, see the wiring of box inside and outside, insulation wrap up has damaged, the metallic part of wire is had bare and bring into contact with is other fittings and box, have give immediately change. Direct perhaps choice has the wire that nylon net laps, also can have better insulation effect so.
3, eliminated wire and electrical outlet the problem of ground connection, in view of the analysis in front, producing the prime culprit with the biggest odds of box leakage of electricity is power source, we begin from power source respect, ravel power source, the EMI circuit that sees power source is integrated, the plastic film between removed component and crust of power source metal piece or the effect that mica sheet loses insulation, power source appears in-house capacitance explode the circumstance such as the oar, be like occurrence problem, can make a piece of high temperature resistant plastic film by oneself, screen is formed to cut off between component and power source crust, be like insoluble power source changes on the horse.
4, check box interior finally advocate board, show clip, the examination appears PCB board is out of shape wait for a circumstance to bring about as direct as box contact. The method of the examination had better be used the smallest change a system, make platform more simple and easy judge on one hand, can avoid the fittings such as hard disk to check the needless attaint in the process on the other hand.
5, itself of final examination box, the face plate before general box is rear, have a link advocate board the PCB circuit with frequency, signal, switch, patulous USB board, we also need to check this circuit board and connector board the case that the wire that go up has short circuit of occurrence insulation invalidation, component, burn down, if have, but the electrical engineering common sense with simple have the aid of and electrical engineering tool its repair or change.
6, of course, we still can arrive through placing box position of relatively dry bright (if put the position to cause electrical wiring short circuit easily damply relatively so) , change the method such as the shoe of bottom insulation, have the judgement of full range, find out prime criminal of leakage of electricity finally.
